Is there a risk of leakage of new energy vehicles in contact with water?

Many electronic devices fall into the water and will be damaged to varying degrees. For electric car owners, when they enter the rainy season, they will also worry that driving pure electric vehicles will encounter serious roads with accumulated water, which may cause electric leakage. So, does this affect the safety of the occupants in the car?

Although people’s fears cannot be underestimated, the truth is not the case. It is important to know that rigorous testing and strict standards cannot consider the safety of vehicles in various environments. It is necessary to say that there is a clear indicator of IP protection level in the product protection safety level: IP protection level.

For power batteries used in new energy vehicles, IP67 is an absolute requirement, while IP67 can be interpreted as protection against dust inhalation (to prevent contact overall, protect against dust penetration); protection for short immersion (anti-immersion).

At the same time, the author also learned through the 4S shop staff that each car must undergo strict environmental testing before going public, ensuring that the cell itself must have strong compression resistance without relying on any protective measures, ability, such as violent testing procedures such as puncture, extrusion, and fire.

In addition, since most of the current new energy vehicle battery packs are arranged on the chassis, it is easier to contact with water during driving. In order to ensure the safety of the battery pack while the vehicle is running, the manufacturer also provides a protection frame for the battery pack. It can provide special insulation protection for the high voltage part of the battery pack, including the safety effects of external forces such as water and collision.

Finally, the software system level is also a security fence. Under the running condition of the vehicle, the power battery management system (BMS) will provide high-voltage electric shock protection, vehicle collision and power failure protection, high-voltage component waterproof protection, high-voltage leakage insulation protection, etc. through monitoring the battery status. In other words, as long as there are any problems, the system will respond to you as soon as possible, keeping the battery in a safe state.
